Sterling silver, Agate and freshwater pearl.  I love these stones, new to me this year.  They have a dramatic rust, black and cream pattern, with a natural edge that dictates their shape, it's evident in the left side earring, not a defect but I did not push the setting into that area which shows a pocket...you can zoom in on the photo to look more closely at that.  2" from the post by 1" wide at the top.
Exchanges only please.
